More than 5,000 national guard and reserve military personnel are based there.The base is adjacent to the Ellington Airport which is a City of Houston Aviation Department facility. Ellington Field Joint Reserve Base is a combined active duty, reserve, national guard and homeland security installation located in Houston, Texas. EFJRB is home for numerous units from all five branches of the U.S. EFJ
RB is part of the larger city-owned Ellington Airport, which hosts both civilian and military aviation operations. The Texas Air National Guard’s 147th Reconnaissance Wing, commanded by an Air National Guard colonel, operates as the host unit for EFJRB due to the aviation focus of the installation, as well as the Texas ANG’s position as the primary military tenant over much of the base’s history. However, the Army Reserve’s 75th Training Command, commanded by a major general (or 2-star) is the senior military headquarters on the installation, and the Navy has the largest reserve troop presence. Ellington Field JRB derives its name from the property’s original military designation when it was constructed as an Army Air Corps training base in 1917. In addition to being the training home of more than 5,000 reservists from all branches, the base serves as a resource to thousands of military personnel in the greater Houston area and 35,000 military retirees and a regional veteran population of about 300,000.
